Research interests

QARMA is the machine learning research team of “Laboratoire d’Informatique et Systèmes” (LIS). The team focuses on three major aspects of machine learning: learning theory, deep learning, and learning in the context of signal processing. QARMA is the to-go team of machine learning in certain theoretical aspects such as spectral learning, grammatical inference, operator-valued kernels, and generalization bounds. The approach to learning and signal processing is
enriched by collaborations with mathematicians from I2M and other laboratories.

The team promotes the benefit of research focused on both fundamental aspects and applications that generate original and challenging problems to investigate. QARMA is part of multiple theoretical and/or applied research projects. Some of the team’s favourite applications are neuroscience, bioinformatics, astrophysics, as well as music, multimedia, and time series.

The QARMA team was founded in 2012 and includes 10 permanent members and ten to fifteen doctoral students and post doctoral research fellows. In the LIS, Qarma belongs to the “pole Science des Données”. The team is primarily located in Chateau-Gombert. Some doctoral students are co-tutored with INT, CPPM, TAGC or University of Quebec.
